Section 3: Electronic Cam Programming Basics

This section contains an introduction to the basic electronic CAM programming concepts. The

Local Logic function, and motion programming are not discussed in detail in this section, since

they are discussed in other chapters in this manual.

Requirements

The Local Logic, CAM Editors, and Motion Program editors are integrated within the VersaPro

version 1.5 or later software. Prior to beginning the “Introduction to Electronic CAM

Programming” section, the user needs to install VersaPro and the CAM Editor. Please reference

the VersaPro documentation for instructions on how to install this software. The DSM314 feature

set also requires 90-30 CPU release 10.0 or higher firmware. Please make sure your CPU

Hardware supports this firmware release and is at or above this revision level. Also, the DSM314

firmware release version must be 2.0 or later.

Introduction to Electronic CAM Programming

The electronic CAM function works in conjunction with the DSM314 motion program, DSM314

Local Logic program, and the PLC programming environment to yield a flexible programming

environment. Specifically, the electronic CAM function allows the user to specify precise position-

to-position relationships between a master axis and a slave axis. This ability is critical to many

applications where very tight synchronization between axes is an absolute requirement.

The DSM electronic CAM function allows the user to specify these position-to-position

relationships using the integrated VersaPro based tool. The CAM Editor tool allows the user to

enter these relationships graphically, in tabular form or a combination of both. These CAM

profiles are then stored to the DSM module where they are accessed through the DSM motion

programs. The basic CAM concepts are simple and are best illustrated with a simple example.

Creating a CAM Application Example

Basic Steps

1. Open the project folder or create a new one

2. Create a CAM block

3. Create a CAM profile

4. Link the CAM profile to the CAM block

5. Configure the CAM profile
